抄録

In the present study, it is described that the removal of aqueous ammonium in wastewater released from the steel industry and thermal power plant is possible in using powder MgHPO₄ while the removal nature depends on the solution pH and various contaminant in the wastewater. The removal rate of aqueous ammonium increased with increase of an initial solution pH. Although apparent removal rate increased upon adding phenol that was contained in wastewater from steel industry, it was found that an addition of an excess amount of NaOH into the solution but not phenol directly contributed to the increase of the removal rate. The removal amount decreased upon adding SO₄^2- and Ca²⁺ that were in wastewater from the thermal power plant.
